Hi folks. Val and Roger were dear friends, and I am on the ground here, and I'd like to respectfully ask that you refrain from speculation. The press is rushing to print sensational items, and they don't know the actual facts. I've been talking to the police directly, and nothing is conclusive yet. Nothing has actually been ruled out, nor determined to be the cause. They don't even have full toxicology reports yet, t…

Could CO be produced by a clogged clothing dryer?

Small datapoint: Gas dryers are pretty rare in the US, but do exist.

Omega is one company I would trust for this myself; they sell for industrial applications, not homes, and have a good reputation when it comes to sensors. A CO monitor will set you back $235. http://www.omega.com/pptst/AQM-103.html

Are there any that work in temperatures below freezing? I'm living in my car and using a propane heater when it gets cold.

If you're able to get a small ceramic heater, you'll find that there are many unexpected places to plug it in. E.g. near gas station car wash exits, some parking lot lamp posts, etc. Check with the owner for permission, there are some that will grant it, especially if you're able to offer some lot cleanup or other bartered assistance for them.

Don't use a propane heater, please. It's dangerous to you and potentially to others nearby.

Do you think there's even a physical possibility with the material used with printers ? Condolences

No, not possible. With the added clarification on the apartment size a laser cutter would have had to have output nearly 1/2 pound of CO. My initial 1.7oz calculation was absurd in thinking that amount of CO could be produced and at 1/2 pound, it's not even worth entertaining.

Which VOC detector do you have? After I purchased my new house (USA, Georgia) I put in the detectors. My wife is from China where people are rightfully paranoid about formaldehyde - due to low quality building material. It's basically the same in the USA, except people are a lot less knowledgeable and informed about it. My cabinets, drywall, paint all had high level of formaldehyde. Had to always had the windows open…

Eve Elgato: https://www.elgato.com/en/eve/eve-room Sadly they do not break it down by substance type (which the website almost suggests it does), but i find it very interesting to monitor and that the measurements are highly correlated with painting or opening a window.

Dang! Eve looks good, especially for the price.

I have Foobot (https://foobot.io/) and looks like it cost twiec as much as eve but probably does the same thing. Though, it doesn't say if eve uses wifi..I just see it say bluetooth. I like how Eve is battery powered, you can bring it wherver you want - whereas Foobot is plugged in.

I have UNI-T UT-338C for on the fly readings. I like how the UNI-T can be portable, or plugged in and has a display. I get similar readings between the UNI-T and Footbot so I can somewhat trust it...

I recently started getting very interested in air quality in my house. I decided to take a similar approach to air quality that I do with the stock market: lots of small, well distribute bets whenever possible. For context, our house is 3 levels with a furnace in the basement (cold climate; Canada) I ended up with 3 different brand of CO detectors, 2 different brands of smoke detectors and 1 radon detector. By far th…

Oh jesus. I'm currently renovating 2 bathrooms at once and ceramic dust is coating pretty much everything else not secured. I didn't even know about VOC's until now. I may have to invest in a detector EDIT: I ended up ordering a Foobot after doing some homework

Oh I feel your pain. We renovated our basement and did a polished concrete floor. Brutal dust, it's just everywhere and I've tried to clean so many times but a few days later I look under something and BOOM missed a spot, it got everywhere! Masonary dust is a special kind of horrible.

It's really rather decent, but I grow to hate the HomeKit protocol more every day (slow, buggy and not something I can mess around with) probably a wise move not going with something apple powered.
